advice please!

Hi, I have suffered from eating disorders and body dysmorphia since a young teen. I am currently getting help and have gained weight while recovering. I have never seen myself at this weight and i’ve been extremely insecure. I used to be much skinner and i felt more beautiful and confident. A guy asked me to go the beach with him as a date I’m not sure the last time i let myself wear a bikini, but i think this might be the time to start ! please help spread positivity to me this is so hard and difficult for me to do, but please tell me if i am worthy enough for this beach date and bikini.
